HTTP symbian example - post not working

[tomasz.florczak]

Hi I have compiled HTTP symbian example app for S60 3rd edition.
I have no problems with get requests (I can send them and they reach server) but when I am trying to send POST reguest I am getting
Error - 7334 (that means empty body)

but actually I am filing the body
I invoke function from symbian HTTP example in this manner:

<code> iClient->IssueHTTPPostL(someAdrressThatIsOK,_L8("text/plain"),_L8("someparameter1=lala"));
</code>

Am I doing sth wrong here ? Does anyone has a working example of HTTP post ??


The IssueHTTPPostL function from the symbian examples looks like this:
<code>

void CWebClientEngine::IssueHTTPPostL(const TDesC8& aUri,
const TDesC8& aContentType,
const TDesC8& aBody)
{
// Parse string to URI
TUriParser8 uri;
uri.Parse(aUri);

// Copy data to be posted into member variable; iPostData is used later in
// methods inherited from MHTTPDataSupplier.
delete iPostData;
iPostData = aBody.AllocL();

// Get request method string for HTTP POST
RStringF method = iSession.StringPool().StringF(HTTP::EPOST,
RHTTPSession::GetTable());

// Open transaction with previous method and parsed uri. This class will
// receive transaction events in MHFRunL and MHFRunError.
iTransaction = iSession.OpenTransactionL(uri, *this, method);

// Set headers for request; user agent, accepted content type and body's
// content type.
RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();
SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent);
SetHeaderL(hdr, HTTP::EAccept, KAccept);
SetHeaderL(hdr, HTTP::EContentType, aContentType);

// Set this class as an data supplier. Inherited MHTTPDataSupplier methods
// are called when framework needs to send body data.

/*
MHTTPDataSupplier* dataSupplier = this;
iTransaction.Request().SetBody(*dataSupplier);
*/
// Submit the transaction. After this the framework will give transaction
// events via MHFRunL and MHFRunError.
iTransaction.SubmitL();

iRunning = ETrue;
_LIT(KConnecting,"Connecting post...");
iObserver.ClientEvent(KConnecting);
}

Hi tomasz.florczak,

The exampleclient at EPOCROOT\Examples\AppProts\exampleclient is working in both the cases GET/POST.

In case of POST we have to set the content type to application/x-www-form-urlencoded see SDK documentation http://www.symbian.com/developer/tec...oderClass.html

So, I think iClient->IssueHTTPPostL(someAdrressThatIsOK,_L8("application/x-www-form-urlencoded"),_L8("someparameter1=lala"));

may also work.

Hi tomasz.florczak
Can you please guide me how to send a simple servlet post get request using C++ Symbian SDK 60 5th edition? I am able topost and get my request/response in j2me but the same i am unable to do in C++ I think it is more complicated then I expected.. Please guide how this can be done.. will be really greatful if you can post some example code .. My j2me code is as below


HttpConnection hc = null;
InputStream in = null;
OutputStream out = null;

try
{
String message = "";
String url = "http://192.168.17.15:29159/WebApplication1/RegisterFriend?mobile="+input1.getString()+"&uname="+input2.getString()+"";
hc = (HttpConnection)Connector.open(url);
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
hc.setRequestProperty("Content-Length",Integer.toString(message.length()));
out = hc.openOutputStream();
out.write(message.getBytes());
in = hc.openInputStream();
int length = (int)hc.getLength();
byte[] data = new byte[length];
in.read(data);
String response = new String(data);
StringItem stringItem = new StringItem(null, response);
LocateFriendForm.append(stringItem);
LocateFriendForm.setTitle("Done.");
}
catch (IOException ioe) {
StringItem stringItem = new StringItem(null, ioe.toString());
LocateFriendForm.append(stringItem);
LocateFriendForm.setTitle("Done.");
}
finally {
try {
if (out != null) out.close();
if (in != null) in.close();
if (hc != null) hc.close();
}
catch (IOException ioe) {}

}
